pregabalin/amitriptyline/duloxetine help please

hi all. I have seen my GP today about my increasing nerve pain. He has given me duloxetine and told my to wean myself off pregabalin before I start the duloxetine. I always read up on any new drug I have. This time I am confused. From what I have read, pregabalin seems to work better than amitriptyline, which is different to what the doctor told me. I am confsed, ca anyone help and put my mind at ease. I am so confused (which seems to happen a lot!)
